The synthesis of a series of extremely bulky secondary amines with a phosphine function, Ar†(PR2)NH (Ar†= C6H2{C(H)Ph2}2Pri-2,6,4; R = Ph, NEt2, NPri2) is described. Deprotonation with eithern-BuLi or KH yields the respective alkali metal amides. Reactions with a series of chlorosilanes allows access to monomeric molecular compounds bearing the extremely bulky amino substituentsviasalt elimination.
